Dozens of undocumented Cambodian migrant workers have been dismissed from a Thai dried-durian factory after being brought there by job brokers, leaving them in a vulnerable state in an incident that underscores the risks of ongoing illegal migration.

Illegal border crossings were on the rise until land borders reopened in May, and undocumented migrants in seasonal work are being left in a precarious state as jobs come and go.

Leong Sophon, project officer for Central, said about 40 Cambodian and 100 Burmese workers were dismissed on June 25 from the Sunshine International in Chon Buri as the durian season came to an end.
